Background and Study Aim. The physical activity level of students is closely associated with ecological, hygienic, and socioeconomic facts. This is especially true during the COVID-19 pandemic, which has dramatically reduced the student opportunity to engage in regular physical activity. The purpose of the work is to study the influence of the weekly physical exercises on the indicators of biological age of students of higher education institutions of Ukraine. Material and Methods. The study involved 409 students (182 boys and 227 girls), who were divided into experimental (87 boys and 117 girls) and control (95 boys and 110 girls) groups. The biological age (BA) of students was determined by means of Voitenko’s method using biomarkers of their physical status. Indices of the cardiovascular system (pulse, systolic, and diastolic blood pressure); respiratory system (vital capacity, the Hench and Stange test); central nervous system (static balancing); PHSA (personal health self-assessment) were studied. In addition, a questionnaire-based survey of students on their health self-assessment including 27 questions was carried out. Statistica 13.5 statistical software package was used to process the experimental material. Methods of variation statistics, correlation, and regression analysis were used. The coefficients of the Student t-test and Fisher’s F-test were calculated.     Results. In the process of pedagogical experiment, the positive impact of the author’s physical education program on BA of students of the experimental group (EG) was revealed: in boys, the positive dynamics of BA changes was detected already after four additional hours of performing exercises per week, whereas in girls – after six or more hours. The most pronounced changes in physical state, which determined BA decrease during academic year were noted in students with a weekly motor regime exceeding 6 hours.  In boys of EG, the biological age decreased at the end of the experiment by 11,1 years (p < 0,001), whereas in girls – by 5,3 years (p < 0,001). No positive changes of BA were observed at the end of the experiment in students of the control group (CG), whose weekly regime of motor activity constituted 2 hours. In boys of EG, the decrease of BA is manifested after four additional hours of performing physical exercises per week, whereas in girls – after six or more hours. The most pronounced changes in BA indices during the academic year were noted in students of the experimental group with weekly motor regime exceeding 6 hours. Conclusions. The developed mathematical models are recommended to be used for estimating, modelling, and predicting the biological age of students according to informative indices of physical state.

The aim of the article was to investigate interconnections between the components of physical fitness and the health level of students. The structure of physical fitness of young men and women was determined, considering the dynamics of their organism development, as well as a correlation of the factors that provide the base of the physical working capacity of future specialists by means of physical education. A systematic theoretical-methodological and empiric analysis of the physical education problems of students of special medical groups in higher educational institutions was conducted. We examined and studied the general patterns, which determine a planning of individual components of health-preserving technologies in the process of physical education of students of special medical groups. During a long pedagogical experiment, the effectiveness of the use of components of health-preserving technologies in the physical education of students of special medical groups was proved.  We identified the essence and a methodological base of implementing components of health-preserving technologies for correcting somatic health of students of abovementioned category. Usage of components of health-preserving technologies in the physical education of students of special medical groups under conditions of pedagogical experiment (aerobic exercises (mainly walking and running), as well as self-improvement training sessions, etc.), caused the increase of body's functional capabilities, and improvement of well-being.

The aim: Is to study the dynamics of students' physical fitness level while differentiating physical education classes in accordance with their somatic health and nosology of diseases. Materials and methods: The paper presents the results of a study of the dynamics of the physical fitness indicators of students in the process of physical education. The study involved 660 students between the ages of 17 and 25. Testing of students' physical fitness was performed using the method of control measurements. Research methods included the theoretical analysis and generalization of scientific and methodical literature, pedagogical observations, testing, pedagogical experiment, and the methods of mathematical statistics. Results: At the end of the experiment, the students of the experimental groups (both male and female) showed authentically (р<0.05–0.001) better indicators of the control tests than the students of the control groups. Conclusions: It was established that the introduction of the original program of differentiating classes in accordance with the level of students' somatic health and nosology of diseases into the process of physical education has a positive effect on their physical fitness level. This will help to improve their learning and future professional activities.
